-------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # SIMPLE-PWA 2 | 本项目是pwa搭载在vue的示例项目，pwa是一个渐进式web应用概念，不依赖任何框架，vue只是一个实现载体。 3 | 4 | ## 概念 5 | [Progressive Web Apps](https://developer.mozilla.org/zh-CN/Apps/Progressive "pwa") 是渐进式Web应用程序，运行在现代浏览器并展现出超级能力。支持可发现，可安装，离线运行，消息推送等APP特有的能力，本项目以最简单的方式封装了以上功能。 6 | 7 | ## demo 8 | ![pwa example](./static/code.png) 9 | 10 | 请使用android高版本（>5.0）最新版chrome浏览器访问。 11 | 12 | ## 目录 13 | - 任务清单，[查看所有可配置项](https://developer.mozilla.org/en-US/docs/Web/Manifest "配置项") 14 | - 离线浏览 15 | - 推送通知 16 | - 工具：[性能工具LightHouse](https://developers.google.com/web/tools/lighthouse "LightHouse")，[sw工具库sw-toolbox](https://github.com/GoogleChromeLabs/sw-toolbox "sw-toolbox") 17 | 18 | ## 开始 19 | ``` bash 20 | # install dependencies 21 | npm install 22 | 23 | # serve with hot reload at localhost:8080 24 | npm run dev 25 | 26 | # build for production with minification 27 | npm run build 28 | ``` 29 | 30 | ## 项目结构 31 | 由于本项目使用vue-cli生成结构，大部分目录同vue项目，重点看/src/sw、index.html。 32 | 33 | > **注意：** 如需开启推送功能，开发时将 sw/ 目录下各文件域名替换为自己的域名 34 | - index.html 35 | - /src/sw 36 | - manifest.json 37 | - register.dev.js 38 | - register.prd.js 39 | - register.simple.js 40 | - service-worker.tmpl 41 | - sw.js 42 | 43 | ## 运行过程 44 | pwa工作依赖于Service Worker（简称sw）。 45 | > 任务清单 -> sw注册 -> sw监听/代理 46 | 47 | 1. 首先在index.html引入manifest.json和用于注册sw的register.js； 48 | 2. 接着register.js会检测navigator.serviceWorker并将sw.js注册； 49 | 3. 最后sw.js持续监听和代理sw事件。 50 | 51 | > 注意：本项目使用copy-webpack-plugin和sw-precache-webpack-plugin将/src/sw下的文件编译并生成到项目根目录下，因此使用<%= htmlWebpackPlugin.files.publicPath %>变量获取 52 | 53 | **index.html:** 54 | ```html 55 | 56 | 57 | 58 | ... 59 | 60 | 61 | 62 | 63 | ... 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | ``` 72 | **register.js:** 73 | ```js 74 | if (navigator.serviceWorker) { 75 | navigator.serviceWorker.register('/sw.js') 76 | .then(function (registration) { 77 | console.log('Registered events at scope: ', registration) 78 | }) 79 | .catch(function (err) { 80 | console.log('ServiceWorker registration failed: ', err) 81 | }) 82 | } 83 | ``` 84 | **sw.js:** 85 | ```js 86 | self.addEventListener('some event', e => { 87 | // do something 88 | }) 89 | ``` 90 | 91 | ## 工作规则 92 | ### 添加到主屏幕 93 | 添加到主屏幕既可安装，需要满足以下条件： 94 | 1. 需要 manifest.json 文件 95 | 2. 清单文件需要启动 URL(start_url) 96 | 3. 清单文件至少需要 144x144 的 PNG 图标 97 | 4. 网站正在使用通过 HTTPS（或localhost） 运行的 Service Worker，既sw处于activated状态 98 | 5. 用户需要至少浏览网站两次，并且两次访问间隔在五分钟之上 99 | 100 | ![添加到主屏幕](https://user-gold-cdn.xitu.io/2018/3/12/16218297564a044a?w=586&h=253&f=png&s=76682) 101 | 102 | ```json 103 | { 104 | "name": "PWA Lite", 105 | "short_name": "PWA", 106 | "display": "standalone", 107 | "start_url": "/", 108 | "theme_color": "#ffffff", 109 | "background_color": "#ffffff", 110 | "icons": [ 111 | { 112 | "src": "./static/appicon_144.png", 113 | "sizes": "144x144", 114 | "type": "image/png" 115 | }, 116 | { 117 | "src": "./static/appicon_96.png", 118 | "sizes": "96x96", 119 | "type": "image/png" 120 | }, 121 | 122 | { 123 | "src": "./static/appicon_48.png", 124 | "sizes": "48x48", 125 | "type": "image/png" 126 | } 127 | ] 128 | } 129 | ``` 130 | 131 | 在chrome开发者工具中： 132 | 1. Application/Manifest 检查manifest.json有效性 133 | 2. Application/Service Workers 查看当前sw状态 134 | 3. Application/Service Workers 调试时可勾选"Update on reload" 135 | 136 | 添加到主屏幕只会显示一次，这在调试过程非常不便。不过，如果你使用chrome调试，可以访问 **chrome://flags/#bypass-app-banner-engagement-checks** 勾选忽略，这样每次访问都会显示。 137 | 138 | ### 离线浏览 139 | sw提供很多种 [缓存模式](https://jakearchibald.com/2014/offline-cookbook/ "缓存模式")。 140 | 141 | sw处于activated状态时，可以在sw.js监听fetch事件并拦截和处理任何请求： 142 | ```js 143 | // 请求命中缓存时直接返回缓存结果，否则发起请求 144 | self.addEventListener('fetch', e => { 145 | e.respondWith( 146 | caches.match(e.request).then(response => { 147 | if (response != null) { 148 | return response 149 | } 150 | return fetch(e.request.url) 151 | }) 152 | ) 153 | }) 154 | ``` 155 | 156 | ![离线浏览](https://user-gold-cdn.xitu.io/2018/3/12/162182ab8a3cddb2?w=592&h=251&f=png&s=56299) 157 | 158 | 在chrome开发者工具中： 159 | 1. Application/Cache/Cache Storage 查看缓存列表 160 | 2. 如果sw拦截成功，在Network中size列可以看到(from ServiceWorker)字样 161 | 3. 在Network中勾选offline然后刷新页面，可以看到已访问过的页面仍然可以访问，并不会出现“未连接到互联网”，这就是离线浏览的威力 162 | 163 | ### 关于浏览器缓存模式 164 | 1. **from memory cache** 内存，只存在浏览器运行时，如base64图片数据和静态资源，不可控 165 | 2. **from disk cache** 硬盘，长期缓存在硬盘中，如静态资源，不可控 166 | 3. **from ServiceWorker** sw代理，完全可控 167 | 168 | ![浏览器缓存模式](https://user-gold-cdn.xitu.io/2018/3/12/162182b497b534ca?w=752&h=144&f=png&s=46193) 169 | 170 | ### 消息推送 171 | ![notification](https://raw.githubusercontent.com/SangKa/PWA-Book-CN/master/assets/figure6.4.png "notification") 172 | 173 | 消息推送需要满足以下条件： 174 | 1. sw处于activated状态 175 | 2. 用户允许通知 176 | 3. 询问用户是否允许的对话框只会显示一次，可以在chrome地址栏点击i图标，将“通知”项改为“使用全局默认设置（询问）”即可发起询问对话框 177 | 4. 用户允许后会得到订阅对象，其中endpoint指向谷歌的推送服务器，因此接收时需要全局翻墙 178 | 179 | ![消息推送](https://user-gold-cdn.xitu.io/2018/3/12/162182bca562924b?w=513&h=263&f=png&s=51909) 180 | 181 | ```js 182 | // 服务器推送事件 183 | self.addEventListener('push', e => { 184 | // do something 185 | } 186 | 187 | // 推送消息对话框点击事件 188 | self.addEventListener('notificationclick', e => { 189 | // do something 190 | } 191 | ``` -------------------------------------------------------------------------------- /src/sw/service-worker.tmpl: -------------------------------------------------------------------------------- 1 | /** 2 | * Copyright 2016 Google Inc.
